Our project is going to look at Gentrification in the King County, WA and the affects it has on minorities and how it is link to growth of Big Tech in Area. We are interested in Gentrification because we have seen how rising house prices and rent have displaced low-income residents and people of colour around the city and we believe that gentrification is a major issue in the region. It’s a topic in which people know about but don’t really know the ramification of it. This report will hopefully shed a light on and quantity gentrification in the region and help people see the unfortunate reality that happens quite frequently on a day-to-day basis.
For this report we will be using Data from the American Community Survey (ACS) conducted by the US Census Bureau and we will mostly be focusing on their 5-year estimates from 2017 – 2019 as they are recent enough that they will provide a more accurate picture of the problems we are facing today. The ACS is an annual demographics survey program conducted by the U.S. Census Bureau unlike the Census which is conducted every 10 years. The ACS surveys a sample of 290,000 households every month on a wide range of demographic, social, economic and housing characteristics. Since it’s on a sample of the population the findings are an estimate. For our analysis we have decided to omit the data for 2020 because of the pandemic and the anomalies associated with the 2020 ACS survey.
